Packaging:
Paper-plastic compound bags or jacket pocket, lined with plastic bag, net weight 25/50/500/800/900/ 1000 KG .
Storage and Transportation:
Ventilation inside the dry storage warehouse. Not on the shelf or open storage of goods, should pay attention to moisture. Transport loading and unloading should be anti-rain, to ensure that drying, packaging from damage and pollution. Certificates can not be mixed with the acids were transported. Put out a fire can be irrigated.
Uses:
In the production of electron tubes, TV tubes, computer monitors glass of raw materials, can be used in the production of optical glass to increase transparency, intensity and refraction coefficient. Also used in the production of welding electrodes, welding to prevent the phenomenon of breaking arc. Potassium sorbate food additive, potassium dihydrogen phosphate raw materials and other products. Spraying can be used for fertilizer, but also the raw material for fertilizer. Can also be used in the production of vat dyes and the dye out of white ice. For removal of hydrogen sulfide and carbon dioxide absorbent. Mixed with soda ash can be used for dry powder fire extinguishing agent. Can also be used as acetone, alcohol production, rubber auxiliary materials and production of Anti-aging agent. Aqueous solution can be used for scouring of cotton, wool degreasing. In addition, for the ink, photographic drugs, polyester, explosives, electroplating, leather, ceramics, building materials, and pharmaceutical crystal production. Used in the production of instant noodles, carbonated drinks in the additives, and bulk to play the role of anti-corrosion. Can also be used for food additive potassium sorbate, potassium dihydrogen phosphate raw materials and other products. |
